Step by Step How to Check Squid Cache Size on Linux Fedora 10

Step by Step How to Check Squid Cache
Size on Linux Fedora 10.

The
step by step example below show how to check squid cache size on Linux system.
The example on how to check squid cache size below is done on the Linux Fedora 10
with squid version 3 installed. Sometimes you may wonder how big squid cache
size that already caching on your hard disk... or may be you need to find out why
oh why your squid not working as fast as it should be. To check why your squid not
perform as well as it should be... on of the place to start looking is the cache
size on system hard disk... may be squid cache size near or 100% full it cache capacity
on the disk that you specify on the squid configuration file.

Check system hard disk size.

1. To start this squid cache size
investigation... we start with check the system disk or your system hard disk..
If the system disk if full, or the capacity is near to 100% of disk size its can
drag your squid server down to her knee (no space left for squid to put the squid
cache). To do this use df command as show on example below to check
hard disk size on Linux Fedora system.

[root@fedora
~]# df -h

Filesystem
Size Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00

262G 4.6G 244G 2% /

/dev/cciss/c1d0p1
190M 30M 151M 17% /boot

tmpfs
1.5G 88K 1.5G 1% /dev/shm

[root@fedora
~]#

Check squid cache location and cache
size setting.

2. Check squid cache configuration
file for the size of squid cache and the location of squid cache directory.
Please note that the squid configuration file squid.conf location on the
Linux system may be differ base on your squid installation setup.

[root@fedora
~]# cat /etc/squid/squid.conf
|grep ^cache_dir

cache_dir ufs /var/spool/squid 10000 16
256

[root@fedora
~]#

Check squid cache size on the hard
disk.

3. Use the du command as
show on example below to check squid cache directory size on the hard disk.

[root@fedora
~]# du -hs /var/spool/squid/

660M /var/spool/squid/

[root@fedora
~]#

Note: This step by step how to
check squid cache size is tested on Linux Fedora 10 operating system with
Squid Cache: Version 3.0.STABLE13 install on the system.
